Sample flavour substances component list when table 5 fermentation time is 8 days
Figure BDA0000456267420000093
Figure BDA0000456267420000101
From different fermentation time aroma components, it is 4 days that the fermentation time aroma component of 8 days is obviously less than fermentation time, is mainly reflected in the variation of sweet osmanthus aroma component.As β-ionone reduces approximately 1 times, Geraniol generation esterification, generates geranyl phenylacetate, and along with fermentation time increases, sweet osmanthus king increase to some extent.For the decline of pear fruit wine Main Fragrance kind, cause the reason of the variation of aroma component, a part is the release along with fermenting process carbonic acid gas, part flavour ingredient volatilization, thereby content reduces; Part flavour ingredient, along with the increase of alcoholic strength is dissolved gradually, content increases; Also have a small part alcohols flavour ingredient, be combined with acids during the fermentation, generate ester class, produce new local flavor.Meanwhile, along with the growth of fermentation time, higher alcohols content reduces rapidly, and the content of ester increases to some extent, is conducive to improve the quality of fruit wine.Therefore, sweet osmanthus pear Fermented Fruit Wine, is different from general assembled alcoholic drinks, is also different from sweet osmanthus, the pear wine of the rear allotment of fermentation separately, because various flavour substances content and character can change during the fermentation, local flavor is more coordinated soft.
Differing temps fermentation comparing result
On the basis of embodiment 1, only change the temperature of fermentation, about then its physics and chemistry and Oranoleptic indicator being divided, as shown in the table:
Physics and chemistry and the Oranoleptic indicator of table 6 pear wine fermented with osmanthus flower
Figure BDA0000456267420000102
As seen from the above table, temperature is also very large for the impact of fermentation, and sample 1 mouthfeel is better, slightly sweet, and wine degree is low, and residual sugar is many; Sample 2 mouthfeels are good, and fragrance is pure, have good typicalness; Sample 3, mouthfeel is poor, easy top, yeast flavour is dense.
Different initial pol fermentation comparing results
Adopt the processing step in embodiment 1, about the fermentations of only setting different just sugar divide for the physics and chemistry of fruit wine and Oranoleptic indicator; Analytical results is as following table:

By table 7, can find out, residual sugar is all lower than 1%, but initial pol is while being 23% and 24%, and alcoholic strength does not have up-trend, and acidity is because yeast has during fermentation produced some acids, makes the reduction of pH value.
After fermentation period finishes, it is better that when initial pol is 20-22%, the wine sample of pear wine fermented with osmanthus flower is tasted result.No matter be that its color, smell and taste or its typicalness are all better.Bright and lustrous, without brown; Its fragrance do not have stink, the smell of fruits is very sweet, the soft association of aroma; Its taste not tool is pained, pure; Its transparency limpid bright, without any suspended substance; Typicalness is also quite good.When just sugar is 23%, mouthfeel is also better, but is cost consideration, selects sugared concentration 20-22%.
The comparative analysis of different initial pH value fermentation results.
Adopt the processing step in embodiment 1, be determined under different initial pH value, fermentation results contrast sees the following form:
Physics and chemistry and the Oranoleptic indicator of the different initial pH value fermentation of table 8 pear wine fermented with osmanthus flower
Figure BDA0000456267420000121
By table 8, can find out, in 8 day time, residual sugar is all lower than 1%, and alcoholic strength is 10.5, and anthocyanidin content is more or less the same, and pH is because yeast has during fermentation produced some acids, and pH value is reduced.After fermentation period finishes, the pol of fruit wine is transferred to 2-3%, fermented wine product are tasted, given a mark.Trial test result is as follows: initial pH3.5 tart flavour is too dense, has covered vinosity, clarification, no suspended substance; Initial pH4.0 vinosity is denseer, and fragrance of osmanthus is obvious, transparent limpid; Initial pH4.5 color and luster is without brown, distinctness, and clearly, tart flavour is just in time for sweet osmanthus pears perfume (or spice); Initial pH5.0 vinosity tart flavour is all lighter, and fragrance of osmanthus and pears perfume (or spice) are not obvious, but transparent clear clear, no suspended substance.By upper table, can show that the fruit wine of gained is best wine sample the initial pH4.0-4.5 in the situation that, no matter be its color and luster, Wen Xiang, taste perfume (or spice) or transparency is all better.
The comparative analysis of different vaccination amount fermentation results
Taking the Angel TH grape wine high activity dried yeast having activated is fermented yeast, adopts 4%, 6%, 8%, 10% inoculum size to test the inoculum size of determining that it is optimum.Initial pH was 4.5, and initial sugar degree is 22%, and juice, than being 1:1, adds 0.4g/100ml sweet osmanthus, 22 ℃ of bottom fermentations 6 days.
The comparative analysis of table 9 different vaccination amount fermentation results
Figure BDA0000456267420000122
During the inoculum size of 6-10%, residual sugar, alcoholic strength, anthocyanidin content are all more or less the same, and 4% inoculum size is because inoculum size is too little, and sugar utilizes not exclusively.Sense organ taste's analytical results: its color and luster under 3% inoculation compared with the color and luster under other inoculum sizes all vivid, coordinate.And the transparency of obtained wine thereby sample is poor under 4% inoculation, have more suspended substance, yet it is all better in color and luster, taste, transparency, typicalness to take the wine sample that 6-10% fermented as inoculum size.
8, different sweet osmanthus dosage fermentation results comparative analysis
Adopt method and step in embodiment 1, only change the addition in dry golden osmanthus, measure the impact that it brings.
The comparative analysis of the different sweet osmanthus dosage of table 10 fermentation results
Figure BDA0000456267420000131
Sweet osmanthus dosage is on not impact of alcoholic strength, and dosage is many, and anthocyanidin is corresponding slightly to be increased.Mainly to affect mouthfeel, fragrance.During 3g/L, Wen Xiang is slightly light, and entrance sweet osmanthus fragrance is also light, but fruital is better, and fragrance of a flower fruital aroma integral body is relatively coordinated, and mouthfeel is better.During 5g/L, sweet osmanthus is added fragrant outstanding, and entrance sweet osmanthus fragrance is better, and fruital can not embody relatively, smell coordination, and mouthfeel is also relatively good.
